High-temperature resistant materials mainly refer to materials that can maintain stable performance and structural integrity in high-temperature environments. Many materials can work stably at high temperatures, some of which can withstand temperatures up to 1,600 degrees Celsius. Here are some common high-temperature materials:
Alumina Ceramics: Aluminum oxide is a common high-temperature ceramic material that can withstand quite high temperatures. It is commonly used in ceramic insulation, refractory bricks, and other high-temperature applications.
Silicon carbide ceramics: Silicon carbide ceramics have good high-temperature properties and can be used under high temperatures, high pressures, and corrosive atmospheres. It is often used in the manufacture of high-temperature stoves, refractory parts, etc.
Silicon carbide fiber: This is a composite material composed of carbon fiber and carbon-based matrix. It has good high-temperature properties and can be used in aircraft, high-temperature stoves, and other fields.
Zirconia: also a commonly used high-temperature material. Zirconia has excellent thermal and chemical stability, making it widely used in high-temperature environments. Zirconia has a melting point of approximately 2,700 degrees Celsius, allowing it to maintain structural integrity at very high temperatures. Zirconia has a relatively low thermal expansion coefficient, which makes it more thermally stable under high-temperature conditions.
Magnesium oxide: a common high-temperature refractory material often used to make refractory bricks, refractory coatings, and other refractory products. It maintains stable performance at high temperatures and has good resistance to chemical corrosion and thermal stress.
Silicon carbide: It has good high-temperature performance and corrosion resistance, so it is widely used in high-temperature industrial applications. It is often used in the manufacture of high-temperature stoves, refractory parts, heat exchangers, etc. Silicon carbide ceramics are also used in the manufacture of cutting tools, ceramic bearings, etc.
Tungsten: Tungsten is a high melting point metal with a melting point of approximately 3422 degrees Celsius. Therefore, tungsten is often used to manufacture high-temperature electrodes, heating elements, etc.
Refractory ceramic fiber: This fiber material can maintain stable performance at high temperatures and is widely used in high-temperature insulation, refractory lining, and other fields.
Platinum and platinum-rhodium alloys: Platinum and its alloys have good stability at high temperatures and are often used in the manufacture of pyrometers, resistance heating elements, etc.
In practical applications, the selection of a specific high-temperature resistant material often depends on specific engineering requirements, cost considerations, and material properties. In addition, it should be noted that some high-temperature materials may undergo phase changes or chemical reactions at specific temperatures, so actual working conditions need to be considered when selecting.
